DHCP relay agent and secondary ip address

[red_lee]

Hi

  I configure some commands on the 3750 as follow：

interface Vlan401

description PC_VLAN01

ip address 192.168.150.2 255.255.255.0 secondary

ip address 10.25.125.2 255.255.255.0

standby 1 ip 10.25.125.1

standby 1 priority 150

standby 1 preempt

standby 2 ip 192.168.150.1

standby 2 priority 150

standby 2 preempt

interface Vlan411

description IP-PHONE_VLAN01

ip address 10.25.134.130 255.255.255.128

ip helper-address 10.25.125.4

standby 2 ip 10.25.134.129

standby 2 priority 150

standby 2 preempt

The dhcp server is windows 2002

The NIC ip address is 10.25.125.4 255.255.255.0

Configure three pools on the windows 2002

The frist pool 10.25.125.0/24   The second pool 192.168.150.0/24 The third 10.25.134.128/25

l had binded 10.25.125.0/24 to the special PCs . I hope that the other PCs can get 192.168.150.0/24

But in fact the other PCs get 10.25.134.128/25

why?

Hi jcarvaja

first of all, thanks for your reply.

I read the documentation

They that discuss the case are different with my case.

My case are dhcp agent relay(ip helper-address) and ip address secondary

as you mentioned

agent relay to allcate ip address - frist prime subnet(10.25.125.0) ,second prime net (10.0.0.0) ,final other subnet
